FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No.253,298, dated February 7, 1882, Application filed November 30, 1881. (No model.)

To all whom itmay concern:

Be it known that I, ISIDOR Krrsnn, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Fire-Extinguishers, of which the following is a specification.

My invention relates to that class of fire-extinguishers that are normally closed and inactive, but are brought into operation automatically during an incipient fire by the melting of fusible connections. The object of rnyinvention is to cause water to be led through pipes located in various parts of a building, andto be ejected through nozzles or perforations in said pipes when a governing-valve that arrests the flow from the main water-supply is opened; and my invention consists in the peculiar construction and operation of improved devices that control and actuate the several operative parts.

Referring to the drawings that accompany this specification, Figure 1 represents a portion of a pipe with my improved operative devices attached. Fig. 2 represents the same in operation.

Similarletters ofreference indicate like parts on each figure.

a is an ordinary water-pipe, provided with perforations b. The fiow of Water from the main supply is arrested by any form of valve,

which valve is kept closed by a key-rod, c, which is held compressed against the operative parts of the valve by a friable truss-brace, E.

f is a swinging arm carrying a hammer, g, kept elevated by a fusible brace, h, or wire h.

d is a coiled spring, which is kept retracted by pressure of the disk of the key-rod c.

When the temperature rises to a given degree the brace h or wire h is fused, and the support of the arm f being thus withdrawn, it falls by gravity, its hammer g strikes and breaks the truss-brace E, causing the coiled spring to expand, opening the valve within the pipe (1, and the whole device assumes the position shown in Fig. 2. flows through the pipe and escapes through perforations b, or any terminal on any of the branches of the pipe (0.

Having now fully described my invention, what I claim is In an automatic fire-extinguisher, the conduit-pipe (1, provided with a spring pressed valve, in combination with the friable truss- The waterimmediately brace Eand swinging arm f, provided with 5 weighted heady and the supporting fusible brace h, substantially as described.
